ASTM A387 Grade 22L Class 1 vs. N06920 Nickel

ASTM A387 grade 22L class 1 belongs to the iron alloys classification, while N06920 nickel belongs to the nickel alloys. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is ASTM A387 grade 22L class 1 and the bottom bar is N06920 nickel.
